Light, high quality, energy saving and environmental protection - the magic weapon of LED TV

With the rapid development of TV industry, in the LCD TV to fully replace CRT became the mainstream of the market soon, many domestic and foreign manufacturers have colorful invariably introduced known as the next generation of display technology "LED TV", even some manufacturers announced a high-profile, LED TV era has come. As a result, a large area of LED TV promotion and new baked, but also ushered in the general concern of its public consumers.

At present, in the domestic market, the first launch of LED TV has Hisense, Samsung, SONY, SHARP four, LG, TCL, SKYWORTH and other mainstream manufacturers at home and abroad are brewing LED new release. Li Lu, deputy general manager of TCL multimedia China business center, told reporters that the current TCL has been able to produce LED LCD TV, optimistic estimates, to March next year, the market share of the product will reach 30%. The deputy general manager of SKYWORTH China marketing headquarters Sun Wei also revealed that at present, SKYWORTH has two LED products, is expected in the second half of this year will focus on the promotion of the market. In addition, LG, Haier and other manufacturers have also said that the next phase will increase the intensity of research and promotion of LED products.

In the trend of many color TV manufacturers push LED TV, LED TV in the end what kind of cutting-edge quality and charm, so that color TV manufacturers and the majority of consumer groups close attention and love. As a new product of concern, there must be an incomparable advantage of its traditional LCD TV, today we will talk about how to replace the traditional TV LCD TV LED several magic weapon to win.

LED backlight TV thinner

LED is essentially a semiconductor device, the core part is composed of a semiconductor wafer type N and type P, a special conductive layer on the P type semiconductor and N type semiconductor interface will, this has also formed the so-called PN junction. Can the PN junction diffusion on the majority carrier of P type and N type semiconductor in the hinder strong, when we applied the forward voltage of PN junction, the current from the anode to the cathode of LED, while the minority and majority carrier in this compound, the excess energy will be transformed into light energy release, which is also called LED light.

More importantly, LED can emit from ultraviolet to infrared light of different colors, different bands, earlier, LED also only a single wavelength of light, not like the incandescent lamp that works even when the blue, red, green and other colors.

LED as LCD backlight, first of all, using the LED backlight LCD panel, the volume will be further reduced; secondly, LED is composed of many of the LED grid, each grid has a LED, so LED backlight can achieve planar light source real plane light source, not only has excellent brightness uniform, do not need a complex optical design, the application of LED LCD can be made thinner, but also can realize the planar light source is true.

In the existing ultra-thin flat-panel TV products, the product is ultra-thin LED TV, SONY LED TV to achieve the 9.9mm fuselage, Samsung LED TV to achieve the 2.99cm body, and the traditional LCD TV, to achieve the design so thin, not only in the technical difficulty difficult to cross, and the cost in the cost is quite big.

Longer life, more energy saving and environmental protection

In the light of life, LED backlight technology is beyond the traditional LCD tv. We know that the ordinary LCD TV backlight service life is generally about 30 thousand hours, even the top LCD TV backlight life is only 60 thousand hours. LED backlight is not such a problem at the present stage, white LED backlight life is up to 100 thousand hours per day, if after 5 hours calculation, a LED using the backlight source of LCD TV can be used for nearly 55 years. Many experts also put forward the results even further room for development, even if consumers are 24 hours uninterrupted use, LED LCD TV is also able to cope with the.

In addition, LED is used as low-voltage driving, it is the use of 5V ~ 24V low voltage power supply, very safe, the design of driving circuit is simple; its stability is better, the internal structure of the planar structure that LED has a strong and excellent seismic performance; finally, the green environmental protection, LED and more it does not have the advantage of using metal mercury is harmful to the environment, more safety and environmental protection; furthermore, LED backlight is energy-saving, because of its low power consumption, LED internal driving voltage is very low, the better power and security.

Visible, in the concept of environmental protection, energy saving, LED TV complies with the development trend of flat-panel TVs to meet the needs of contemporary consumers.

More prominent picture

In terms of color performance, LED backlight has obvious advantages. We know that the traditional CCFL backlight because of color purity, poor performance in color, which causes the liquid crystal on the gray and color transition as CRT.

According to the test, the use of CCFL backlight can achieve only sixty or seventy of the NTSC color area, and the application of the LED backlight, the LCD panel can easily achieve the performance of the NTSC color gamut of 100%. Like SONY Bravia series LED backlit LCD TV on the choice of the wavelength of the LED with the best color filter, color gamut can reach 126%.

In addition, LCD TV mainly uses CCFL (cold cathode fluorescent lamp) as the backlight; and LED TV backlight is LED (light emitting diode), each LED pixels are in accordance with the brightness of the image, making LED
